I have made a python app on Catalina (self extracted without any need of installation), which is comes for free with one of my products (tsakalisaudioworks.com/products/multicab4/). The app works fine if I run it by transferring it via USB flash on Mojave, Catalina & Monterey OS. BUT when I uploaded it on my website and then downloaded to the above Mac OS it works fine only at Catalina. On the Mojave and Monterey works with some limitations which are: the app cannot open the pdf help file (it opens if I double click on it) the app cannot open the settings.json file which contains some default settings for the app (The file can be opened with double click on it). Seems that Mojave and Monterey OS does not give access to these files via the app. I have compressed the app folder as tar.gz in order to uploaded. Same thing happens if I download the app through cloud (dropbox, onedrive, etc) Any ideas? Thanks Chris
